I think I may be infertile

Kat
So 2009 I got pregnant, I ended up miscarrying and going through hell.
​Ever since 2009 I've had 3 different boyfriends who I've never got pregnant with but they now have children so the finger points at me. 4-5 years and still no baby again. I've been with my partner now for 2 years and nothing :( are there any tabs I can take to help me get pregnant as I don't want to go the doctors and find out I may be infertile. It would break me. I just want a baby again x
